This. invention relates tordev ces used 1n typewriting machines, {for Yholding stenci 1-, cards and the like to be typedupon. The backing, ofthe card-holder, formed of celluloid orlike-materiah'is attached by itsand eXte-ndsin front thereof to overlie the printin field. The, sheet isfolded top edge .to the platen,

lower portion of said celluloid upwardly'atthe front'to form apocket tohold the stencil-card, The 'card holder readily bendable around theplaten, and'isi The top of the celluloid backing-sheet may be attachedto the platen byimeans of a bar suitably fastened to the backing, andextendsaid bar being'bent to form fo'rkedarmsto f bestride flattenedportionsof the hubs of the usual platen ends; Claws at the freepends ofthe forked arms catch over .thelf platen V visionvof means for embodyingp p V Figure 2isa'view in 'slde elevatlomapartly down and shaped 7Figure 3 isa sectional View, taken onit-he Liwhich best'rideflattene'dfa'ces 1321011 th'ehubsf ends.
